The Bureau of Statistics has made a mistake in its latest report on the Australian wine industry.

Figures in the 2009 Australian Wine and Grape Industry report stated that New South Wales had overtaken South Australia to become the country's largest wine producing state, putting out more than one million additional litres.

But the Bureau later said a mistake had been made in the adding up.

The correct figures show South Australia producing 82 million litres more than New South Wales.
